ScrapeBox - Ignore Google TickBox

I know this is silly but I had never thought about it before, until I noticed some interesting chatter on IRC. When Im testing proxies I use two types of testing.

1. For harvesting I use the tests on Google functionality as I harvest most of my urls from google.
   
2. For posting I tick the Ignore Google Tick Box as I want more proxies and Im not interested in whether they are burnt on Google.

Im sure there is an in-depth explanation which would help people greatly. Has anyone got all the details on this in a tutorial which they would like to share?

You don't really need a tut or in-depth explanation, bascially you're doing it right.

I knew I was but thought I would give the opportunity for someone to copy and paste some indepth explanation from one of their ebook guides. Or even give someone the chance to plug one of there own ebooks
